Greenland ice is melting 7 percent faster than previously thought
2016-10-14 12:00:00| LifeSciencesWorld
[NEWS] COLUMBUS, Ohio—The same hotspot in Earth's mantle that feeds Iceland's active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland. According to a new study in the journal Science Advances, the hotspot softened the mantle rock beneath Greenland in a way that ultimately distorted their calculations for ice loss in the Greenland ice sheet. This caused them to underestimate the mel…

Melting Greenland ice threatens to expose Cold War waste

Agence France-Presse: A snow-covered former US army base in Greenland -- dubbed "a city under ice" -- could leak pollutants into the environment as the climate changes, raising difficult questions over who is responsible for a clean-up. In 1959, US army engineers began constructing a futuristic project in northwestern Greenland that might as well have been lifted from a Cold War spy movie. A network of tunnels under the snow contained everything from research facilities to a hospital, a cinema and a church -- all powered...
Greenland may be losing ice even faster than we thought

Washington Post: Rapidly melting Greenland may be shedding its ice even faster than anyone suspected, new research suggests. A study just out in the journal Science Advances finds that previous studies may have underestimated the current rate of mass loss on the Greenland ice sheet by about 20 billion tons per year. Generally, scientists estimate ice loss in Greenland (and elsewhere around the world) using data from satellites. But the new study suggests these satellite studies may have included some incorrect...
Global warming: Greenland ice melting 7 per cent faster than thought

Press Trust of India: Greenland lost nearly 2,700 gigatonnes of ice from 2003-2013, 7.6 per cent more than previously thought, a new study has found. According to researchers from Ohio State University in the US, the hotspot that feeds Icelands active volcanoes has softened the mantle rock beneath Greenland in a way that ultimately distorted their calculations for ice loss in the Greenland ice sheet. This caused them to underestimate the melting by about 20 billion metric tonnes or 20 gigatonnes per year. That means...
NASA Has Mapped The Fragmented Underbelly Of The Greenland Ice Sheet

IFL Science: Thanks to a combination of climatological quirks and man-made climate change, the Arctic is warming faster than anywhere else on the planet, and the Greenland Ice Sheet the worlds second largest is being obliterated at a remarkable rate. A new study, published in the Journal of Geophysical Research Earth Surface, reveals that something rather unfortunate is also going on beneath Greenlands ice. Using a combination of modeling and imaging techniques, scientists have produced a subglacial...
